ENDOSCOPIC ULTRASOUND
It is a procedure that helps in assessment of the gastrointestinal & lung diseases. Endoscopic Ultrasound is a combination of two procedures - endoscopy and ultrasound. Endoscopic ultrasound helps diagnose upper & lower digestive disorders. EUS is an outpatient procedure and takes about one to two hours.
Why is EUS required?
EUS can help diagnose many gastrointestinal disorders such as:
- Identify Stage of colon cancer, lung cancer, pancreatic cancer, stomach caner & rectal cancer.
- Pancreatic disorders such as chronic pancreatitis
- Detect abnormalities in gallbladder and liver
- Detect stones in biliary ducts
- Identify causes behind accidental bowel leakage
- Analyse Nodules in the lining of the intestines
How to prepare for the procedure?
The patient has to follow specific instructions prior to the procedure.
- Patients undergoing EUS of Upper GI tract are recommended to not consume food or beverages for at least 6 to 8 hours prior to the procedure
- Patients undergoing EUS of lower GI tract need to have their colon cleared and may need to use laxatives or enema. They are also asked to follow a liquid for a day prior to the procedure
- Patients may also be asked to temporarily stop medications.
What to expect during an Endoscopic Ultrasound?
During the procedure, a sedative is administered to the patient through an IV. The doctor will then insert the endoscope into the patient’s mouth in case of Upper GI and into the patient’s rectum in case of lower GI. The doctor performs a biopsy
FAQs
Endoscopic ultrasound (EUS) is a procedure that combines endoscopy and ultrasound to get detailed images of the digestive tract and nearby organs. It helps evaluate conditions in the pancreas, bile ducts, and gastrointestinal wall.
It is recommended when detailed evaluation is needed for conditions like pancreatic cysts, tumors, bile duct abnormalities, or unexplained abdominal pain. A gastroenterologist in Hyderabad may suggest it for precise diagnosis.
Unlike standard ultrasound, EUS places the ultrasound probe close to internal organs using an endoscope, giving highly detailed images. It provides more accuracy than external imaging methods.
No, it is usually performed under sedation, so patients remain comfortable during the procedure. Most patients do not feel pain and may not remember the procedure afterward.
The procedure typically takes 30–60 minutes depending on the case. Patients are observed for a short time afterward and can usually go home the same day.
EUS is generally safe when performed by an experienced gastroenterologist. Rare risks may include mild discomfort or bleeding, especially if a biopsy is taken.
